" To all whom t may concern:

Be it known that I, LANSING ONDERDONK, a citizen of the United States,residing at New York, in the county of New York, State of New York, haveinvented certain new and useful Improvements in Oversea'mingSewing-Machines, of which the following is a description, referencebeing had to the accompanying drawing and to the letters and figures ofreference marked thereon.,

My invention relates to new and useful improvements in overseamingsewing machines, and more especially to overseaming' machines of thetype known in the art as glove sewing machines, although it will beobvious from certain aspects of the invenjtion, that parts thereof maybe used in other types of machines.

An object of the invention is to provide a machine of the abovecharacter, 'which is especially adapted for vhigh speed. To this end, Ihavelprovided a system of levers, links and eccentrics, which arepositively connected together for giving to the needle bar and thelooper their various movements.

A further object of the invention is to reduce to a minimum, theoperating parts for the looper, whereby the wear on the parts of themachine is reduced, and the operating mechanism simplified.

The invention further consists in various details of constructionhereinafter described and pointed out in the appended claims.

In the drawings, which show by way of illustration one embodiment of theinvention, Figure 1 is a sectional view rthrough the casing, on the line1-1 of Fig. 3, showing the operating parts in side elevation; Fig. 2 isa top plan view, with the top of the machine removed, showing theoperating parts in plan; Fig. 3 is a sectional view ou the line 3-3 ofFig. 1; Fig. 4 is a sectional view on the line 4-4 of Fig. 1; Fig. 5 isa perspective view of the parts adjacent the stitching point; Fig. 6 isan enlarged perspective view, showing the needle entering the looperthread loop; Fig. 7 is a view partly in section, showing the position ofthe needle and looper when the needle reaches the extreme end of itsstroke; Fig.v

`The machine as herein illustrated, consists of a box framework, whichhouses the operating parts forV the needle, looper and feedingmechanism. The needle lnoves back and forth in a horizontal plane, andthe looper is given six motions, so as to carry the looper into theneedle loop on one side of the line of feed; then over the line of feedto the other side thereof, where it is moved back to withdraw the looperfrom the needle loop. The feeding wwcham'sm.-The feeding mechanism, asherein shown, consists of two feed wheels or cups, l and 2. The feedwheel 1 is mounted in a bracket 3 secured to the box-like framework 1.The feed wheel 1 is mounted on a vertical shaft, carrying at its lowerend the friction ring 5, which is engaged by friction clutches 6,carried by an oscillating lever 7. The oscillating lever 7 extendsthrough a slot in the frame or to a slotted lever 10, fulcrumed at 11 ona bracket carried by the frame or` casing 4. The lever 10 has an armextending to the inside of the casing 4,v where it is pivoted at 12 to alink 13, which in turn coperates with an eccentric mounted on the mainshaft 14, which extends horizontally through the frame or casing 4, andis mounted in suitable bearings carried thereby. A driving wheel ismounted on each end of the shaft 14, as is common in this type ofmachine.

It will be obvious that as the main shaft rotates, the link 13 willvibrate the lever 10, which in turn through the link 8 will vibrate theclutch lever 7, thus imparting an intermittent rotating movement to thefeed wheel or cup 1.

The feed wheel or cup 2 is carried by an `arm 15, which is attached tothe end of a bar 16, mounted to reciprocate in bearings 17 and 18 formedin the frame orcasing 4.

- The bar 16 -carries a collar 19 at its rear end,

which is provided withv a projecting arm 20. A spring 21 is forkedat'its lower end to straddle an adjustable screw 22, and intermediateits end said spring bears against a fulcrum block 23, carried by' thecasing 4. (See Figs. 1 and 14.)

The spring 21 normally tends to hold the bar 16 drawn within the casing,and the feed wheel or cup 2 in VContact with the feed wheel or cup 1'.The feed wheel 2, as herein shown, recelves its movements through itscontact with the fabric being stitched. Itis obvious, however, that saidfeed wheel may be positively driven from the shaft operating the feedwheel 1, in the manner well known in this art.

As a means for moving the feed wheel 2 away from the feed wheel 1 toinsert the work, I have provided the usual hand lever 24, which ispivoted at 25 to the casing of the machine, and coperates with a pro]ecting arm 26, carried by the arm 15 which supports the feed wheel 2. It issometimes desirable to move the feed wheel 2 away from the feed wheel 1,by means of a treadle, and in order to accomplish this, I have provideda lever 27, which is fulcrumed at 28 on a bracket carried by the casing,and said lever at its upper end extends into the path of movement of thebar 16, so that when the said lever is depressed by a treadleconnection, the bar 16 is moved to carry the feed wheel 2 away from thefeed wheel 1. A spring 29 operates to hold the lever 27 'with its upperend out of contact with the bar 16. A pin 30 limits the upward movementof the lever 27.

Needle mechanz'swa-The needle 31 (see Fig. 5) is clamped in the needlehead 32. carried by the needle bar 33. Said needle is mounted so as toreciprocate in a horizontal plane back and forth across the upper edgesof the feed wheels 1 and 2. The arm 15 supporting the f yoke by means of-a lever 51.

v51 is connected feed wheel 2, has a slotted needle guide 34, which isof the usual construction in this type of machine.

The needle bar 33 (see Fig. 1) reciprocates in bearings and 36. A collar37 is secured to the needle bar intermediate its ends, and saidcollar'37 is secured to a lever 38 by means of a link 39. The lever 38at its lower end is pivoted to a rod 40, which extends across the casingand is mounted in bearings 41 and 42, carried thereby, (see Fig. 3). Thelever 38 is pivoted intrrmediate its ends to an eccentric rod 43, whichengages an eccentric on the main shaft 14. As the main shaft rotates,the' lever 38 will be rocked back and forth about its pivotal connectionwith the rod 40, and in turn will impart to the needle bar 33, areciprocating ing a thread.

The looper-carrying rod 45 is mounted so as Ato reciprocate in a pivotedyoke 46. The said yoke is carried by a pivot bolt 47, which extendsthrough a bearing 48 located substantially midway between the ends ofthe looper carrying rod 45. Said yoke 46 has spaced bearings 49 and 50,in which the looper-carrying rod reciprocates. The looper isreciprocated back and forth in the Said lever at its upper end to acollar 52, which is loosely mounted'betweenY bearings 53 secured to thelooper-carrying rod. Said collar 52 carriesl a stud which projectsthrough a ball loosely mounted in the 'upper end of the lever 51. Thisconnection allows the collar to oscillate on the looper-carrying rod,and said rod to move up and down relative to the lever. The lateralmovements of the collar due to the oscillation of the lever k,51, areimparted to the looper-carrying rod.

The lever 51 is pivoted at its lower end to the bar 40. The lever 51 isoscillated about its fulcrum connection with the rod 40, by an eccentricrod 54, which coperates with an eccentric carried by the main shaft 14.The above described mechanism will impart a back and forth movement tothe loopercarrying rod, which moves the looper from one side of the lineof feed to the other side thereof.

'W hen the looper moves from one side of the line of feed to the other,it is necessary to lift it over the edge of the material. This isaccomplished by oscillating the yoke 46 about its pivotal connectionwith the 'casing. Asa means for oscillating the yoke,

the end of a looper-- VThe looper has the usual eyes forA receiv-Vvpivoted at 56 to a lever 57, which is fulcrumed at' 58 on a lbracket 59,carried by the frame or casing 4.

The lever57 is connected by a link 60 to the lever 51, so thatas thelever 51 is oscillated back and forth by the eccentric on the mainshaft, the lever 57 willl also be oscillated back and forth on itsfulcrum 58. The pivotal connection 56 between the lever 57 and the link55 Ais so disposed that said pivotal connection will move from one sideof a vertical line passing through the fulcrum 58 of the lever and thepivotal connection between the link 55 and the bearing 49, to the otherside of said vertical line.

It will thus be seen that for 'one recipro cation of the lever 51 andthe lever 57, the yoke46 will be moved up and down. As thelooper,ftherefore, moves from-a position on one side of the line offeed, it will be raised over thefabric and lowered again on the otherside of the fabric.

In order `that the looper may be moved into and out of the needle loop,I have provided the looper-carrying rod with an arm 58, which is mountedon the extreme rear end of the looper-carrying rod 45. Said arm carriesa ball on its outer end which in turn is connected with an eccentricstrap 59, coperating with an eccentric mounted on the main shaft 14. Asthe shaft 14 rotates, the eccentric strap 59 will swing the arm 58, thusimparting an. oscillation to the looper-carrying rod, which in turn willcarry the looper into and out of the needle loop and move the same backand forth, so as to position the looper, whereby the needle may passbetween the body of the looper and the looper thread.

Needle thread controlling mechanism.- The needle thread is led from thesupply spool 60 through a thread guide mounted on the top of the casing;thence through a suitable tension to a thread-guiding eye 61, carried bythe casing. From the threadguiding eye 61 (see Fig. 5), the threadpasses through ya thread clamp 62, carried by the needle head, andthence to the eye of the needle. The `thread clamp is operated to clampthe thread by means of a roller 63, carried by a bracket arm 64, pivotedat to the casing, and yieldingly pressed forward to engage the threadclamp by means of a spring 66. When the needle bar is fully retracted,the needle thread is brought into contact with an arm 67, caxried by anadjustable plate 68 mounted on the bracket arm 64. The outer face of thethread clamp 62 is oval, as shown in Fig. 15. The spring 66 surrounds abolt 66a, which passes through an elongated opening in the 65'bracketarm 64. By adjusting the screw .spool 69 through a` guiding eye '66, themovement of the roller 63 toward the thread clamp is limited. The curvedface of the thread clamp will, therefore, engage the roller 63 atvarying periods, as the screw 66a is adjusted. By the adjustment of thescrew 66, the time at which the needle thread is clamped is varied. Whenthe needle moves forward into the material, the thread clamp 62 will bebrought into contact with the roller 63, and the needle thread clampedso that the needle in the latter part of its stroke, will draw up theprevious needle loop, which at this time is dropped from the looper.Vhen the needle reaches the rear end of its stroke, the needle threadwill engage the arm 67 and the previous stitch will be drawn tight.

Looper-thread operating mechanism.- The looper thread 1s led from thesupply 70, and' a suitable tension 71, to a second thread-guiding eye72, carried at the front of the casing. From the thread-guiding eye 72(see Fig. 5,) the looper thread passes through the guiding eye 73 on thelooper-carrying rod, and thence through the eyes of the looper. As thelooper is oscillated, so as to be withdrawn from the needle loop, thethreadguiding eye 73 moves away from the thread guide 72, thus drawingup slightly on the looper thread. The looperthread may be threadedthrough the eye 72, then through the guiding eye 73 on thelooper-carrying rod, and then back through'the eye 72, and from the eye72 to the looper. By this threading, more looper thread is pulledthrough the tension. By threading the thread double through the guidingeye 73, as above noted, and adjusting the arm 67 so as to pull off verylittle if any needle thread when the needle bar moves back, a whipstitch may be formed, that is, a stitch in which the looper threadextends from the needle puncture on one side around the edge to the.needle puncture on the other side of the fabric. By threading themachine as shown in Fig. 5,and settlng the arm 67 so asv to pull offmore needle thread, a purl stitch may -be formed, that is, a stitchwherein the needle loops and looper thread loops interlock at the edgeof the fabric.

As a further means for controlling the looper thread, or rather forpositioning the looper thread so that the needle will with certaintypass between the body of the looper and the looper thread as it movesforward into the material, I have provided a looper thread deflector 74,which as herein shown, is secured to the shank of the looper by thescrews 75. Said deector has a forwardly projecting finger76, whichextends in the general direction of the body of the looper, and isspaced slightly therefrom, (see Fig. 6). lVhen the looper moves forwardinto the needle loop, said delector Secures no function. When, however,the looper is carried over the edge of the fabric, and lowered so as toposition itself for the needle, the finger 76 of said defiector engagesthe looper thread, depressing the same, together with the needle loop ofthe previous stitch surrounding the looper, so as to hold the looperthread away from the body of the looper and form a roper space so thatthe needle will enter w1th certainty between the looper thread and thebody of the looper. Said needle as it moves forward moves over the topof the deflecting finger 76, and between the same and lthe body of thelooper, as clearly shown in Fig. 6. Said finger, however, is spaced asufficient kdistance at its free end from the looper, so that saidlooper and said finger may be retracted, leaving the looper thread loopon the needle. E ige guide for fabric- In order to guide the upper edgeof the fabric and hold the same in proper position relative to theneedle, I have provided an edge guide 77, which is secured to a bracket78, mounted on the frame orv casing 4. Said edge guide 77 extends alongthe inner face of the feed wheel or cup 1, and is bent over the edge ofcup 2, so as to extend over the edge of the fabric passing through themachine. Said guide is cut away at the stitchin point, in order toprovide sufiicient room or the operation of the stitch-formingmechanism.

In certain classes of work, such as stitching knitted fabrics, it isdesirable to provide a fabric rest to support the material against thethrust of the needle. It is also desirable in this class of work toprovide a stitch finger over which the stitches may be formed. In Figs.16 17 and 18, I have shown a modified form of construction ernbodyingthese features. The needle guide 34 is recessed to receive the shank 8Oof the fabric rest 81. This fabric rest extends to a point adjacent theneedle path, and has its outerface coincident with the outer face of thefeed wheel. The stitch finger 82 is carried by a shank 83, which is alsomounted in a recess in the needle guard. The stitch finger extendsacross the needle path slightly above the same. Said stitch finger alsoextends over the upper edges of the fabric, and will prevent the samecreeping up during the feed of the fabric through the machine.

In the operation of my machine, the toggle levers will raise and lowerthe looper carrier twice for each oscillation of the looper caused bythe eccentric strap 59. By changing the timing of the eccentricoperating the strap 59, also the eccentric operating the eccentric rod54 and the position of the loo er carrier, I am able to secure varied dierential movements in the looper. In Fig. 19, I have showndiagrammatically the path of movement of the point of the loo er. Inthis figure, :v-a: indicates the line of eed and y--y indicates the lineof reciprocation of the needle. The looper enters the needle loop at thepoint a, and the needle enters the looper thread loop at the point b.The looper moves forward in substantially a straight ath, and is ivensubstantially a dwell while the looper 1s being moved laterv allytoposition its loop for the entrance of the needle. After the needle pointhas entered the looper loop, the looper is retracted but slightly atfirst and is moved laterally, carr ing with it the needle loop which ison its shank untily the looper is substantially over the fabric edges,or at 'the point c, Fig. 19, when said looper will be quickly retracted,shedding the needle loop and moving to the rear end of its stroke inposition to again move into the needle loop.

In Fig. 20 I have shown a modified construction whereby the loopercarrier may g5 Vbe adjusted. The frame has a hub 86 which is providedwith a `horizontal slot 87. The looper carrier stud 88 on which thelooper carrier is mounted to swing, extends through said slot, and has alocking nut 89. Adjust- 90 ing screws 90 extending into said hub, engagethe sides of thestud 88. By loosening the nut 89, the stud 88 can bemoved one way or the other, and held in adjusted positions by the screws90, 90.

In Figs. 22 to 24 inclusive, I have shown a modified form of theVarrangement of the stitch finger. As herein shown, the stitch finger 83ais screwed to the bracket 78, and projects over the feed wheels 1 and 2.

The path of the needle is indicated by the line N-N, Fig. 22. The fabricrest 80 is carried by the needle-guiding member 34. As shown in Fig. 23,the stitch finger 83 has a projecting portion which overlaps the fabric1( support 80". The stitch finger on its under face, and also the fabricide, are cut away to afford a passageway or vthe upper edges of the feedwheels. The fabric passes up between the fabric rest and a shoulder on11 the stitch finger, and the overlying portion of the stitch fingerwill prevent the fabric from rising too far.

When it is desired to take a deeper bite into the fabric with theneedle, the stitch fin- 11.

ger 83a is removed, and a thicker stitch finger 83b is substitutedtherefor.v Also a thicker fabric rest 80h is substituted for the fabricrest 80, as clearly shown in Fig.4 24. This will allow the fabric toextend a greater 12 distance above the edges of the feed wheels and theneedle to take a deeper bite therein.
